GAS-BURNER.

Specification of Letters Patent No. 23,441, dated April 5, 1859-.

To all whom it, may concern:

Be it known that I, VVILLIAM BLAKE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Gas-Burner; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which Figure 1, is a top view; Fig. 2, a front elevation, and Fig. 3, a vertical section of one of my improved burners; Fig. 4:, is a top view, and Fig. 5, a side elevation of it as it appears when divested of the outer casing of its expansion or et chamber.

The nature of my invention consists in the arrangement and application of one or more tubes of small bore or the equivalent in the burner or its chamber and so as to project upward from the bottom thereof, and the gas entrance passage or passages, in a spiral or inclined direction with respect to the bottom of the chamber, and to discharge the gas above the said bore. And my invention further consists in an annular outlet orifice in combination with such means of producing spiral or helical currents within the burner chamber.

The chief advantages of my invention with respect to the common or other burners are as follows: First. By causing the gas to circulate through the burner chamber in one or more helical or spiral curves, the tarry con densed matter will be more evenly deposited over the inner surface of the chamber and thereby not be so likely to choke the inlet orifices. Second. The gas is more evenly presented to the outlet orifice or orifices at the top of the burner and thereby the flame is less liable to spear or fork. Third. It prevents most if not all noise or singing of the burner. Fourth. The flame having a helical current is maintained at an even height with little tendency to flicker or smoke.

The drawings exhibit an Argand burner, having my improvements applied to it.

In such drawings, a denotes the gas receiving expansion or jet chamber of the burner, while 6, and o, are the lateral supporting conduit tubes or arms extending from the short coupling tube cl. The outer and inner casings of the chamber a, are shown at e, and f, while g, is the base thereof, which in this instance is an extension of the inner casing under the outer one.

In carrying out my invention I make or helical or spiral current. For this purpose,

I prefer to use one or more pipes, h, h, of

very small bore, each of which should extend from the conduit, Z), or c, and above the base, g, and at an inclinationto the same, or in a spiral or helical direction, the inner or upper or discharging end of the pipe being made to terminate at about one third of an inch distant from the bottom or base of the chamber a.

The upper end of the chamber, a, may be formed in the usual way with a series of jet orifices or what is better, a continuous, circular or annular opening 2', as in the latter case, the gas will flow out of the chamber, and rise above it, in one or more helical currents whereby its tendency to fork and flicker will be more or less overcome.

\Vhen the burner is furnished with a series of jet orifices at top and with the means of causing the gas to circulate in helical currents through the chamber of reception, the gas will be more uniformly diffused against the series of outlet orifices than when it passes directly or vertically upward from one or two external conduits. In this case, although the flame will be improved it .will not be prevented from flickering as it will when the jet opening is an annulus or ring as shown at i.

I am aware of the subject of the United States Patent No. 16,848, which consists in a single removable disk arranged in the throat of an ordinary fish tail burner and having a helical passage arranged over it and in the body of the burner or a plug, whereby the gas in passing from the supply pipe to the exit passages is caused to pass through the entire helical channel in contact with the heated surfaces and shell of the burner, the object being to effect a thorough and perfect combustion of the carbon. I lay no claim to a burner so made, as my invention has reference to an Argand burner.

Although my invention causes the gas to move in one or more helical currents previous to its escape from the outlet orifice or orifices, the peculiar construction and arrange ment of the conduit tubes 72,, 12 in the burner or jet chamber and with reference to the inlet passages of the base of the chamber, not,

only operates to prevent noise or singing of i the burner, but it spreads the gas uniformly against the inner surfaces of the chamber and prevents the tarry deposit from choking the inlet orifice. The tar as it forms or is deposited in the chamber cannot run down into the inlet orifice, as it will in the gasburner described in the said patent, because it is received in a chamber surrounding and extending below the tubes 7:, h. Hence, it will be seen that their arrangement within the burner and with reference to thelexpansion chamber is very different "from that of the helical passage of the fish tail burner exhibited in the said patent. Therefore in the Argand burner constructed with a gas expansion chamber a, provided-with one or Y -more inlet orifices, passages or tubes 6, 0, ap-

plied to its base,

I claim- 1. The arrangement of one or more conduit tubes, h, h, in the burner or jet chamber and with respect to the base of the said burner or jet chamber and its inlet passage or passages as described.

2. And in combination with the arrangement of theinlet= conduit or conduits in such manner as to cause the gas to pass around in the expansion jet chamber in one or more helical currents, I claim an annular or ring exit orifice 71, whereby the current or currents of gas may be thrown out of the burner in one or more helical streams so as to equalize the height of the flame and prevent it from flickering.
